Add -package mtl ?

thanks, that worked... So, I do not need to "improve" my configuration, but rather I should remember in which package live some functions, and specify those each time? ok, thanks.

Dear all,

When I compile simple programs with monads, I receive following error:

example18.o(.text+0x2de):fake: undefined reference to `ControlziMonadziCont_zdfMonadContCont_closure' example18.o(.text+0x422):fake: undefined reference to `ControlziMonadziCont_zdfMonadContCont_closure' example18.o(.text+0x16f5):fake: undefined reference to `__stginit_ControlziMonadziCont_' example18.o(.data+0xa8):fake: undefined reference to `ControlziMonadziCont_zdfMonadContCont_closure' example18.o(.data+0xe8):fake: undefined reference to `ControlziMonadziCont_zdfMonadContCont_closure'

When I do ghc E:\apps\ghc-6.4\libHSmtl.a -o example18.exe example18.hs all is fine.

For some reasons, libHSmtl.a is not seen by default.

What I am missing?

I feel this is configuration problem, but I afraid editing "package.conf" or alike, because I'll probably make situation worse.

TIA.
